UNITED STATES PATENT OFFICE. I

HENRY W. MATHER, OF BLOOMINGDALE, AND JOSEPH KEARNEY, OF MILL- BURN, NEWJERSEY, ASSIGNORS TO SAID MATHER.

FABRlC FOR CARPET-LINI NG.

SPECIFICATION forming part of Letters Patent No. 261,865, dated August1, 1882.

Application filed November 22, 1881.

To all whom it may concern Be it known that we, HENRY W.'1VIATHER andJOSEPH KEARNEY, both citizens of the United States, the former residingat Bloomingdale, Passaic county, New Jersey, and the latter residingatMillburn, Essex county, New Jersey, have jointly invented an ImprovedFabric for Carpet-Linings and similar Purposes, of which the followingis a specification. 7

The distinguishing feature of our fabric is that it is composed of oneflexible homogeneous sheet with one plain smooth face and one facecovered or studded with elevations in the nature of numerous smallelastic cushions.

These cushions are made by forming depressions in one face of the sheetby pressure, the material being in part compressed and in partdisplaced, that which is displaced serving to I elevate the adjacentcushions or raised parts above the general or normal level of the sheet.We prefer to employfor our fabric some felted material. The depressionsand elevations may bof any shape, and may be formed by compression withany mechanism, We contemplate employing a properly-engraved roll; butother means may be used. The depressions may be formed while the paperorfelt is in process of making or afterward, as desired.

In the drawings, wherein our improved fabric is illustrated, Figure 1 isa plan view of the upper or roughened side, and Fig. 2 is across-section of the same on the line 2 2 in Fig. 1.

Let a arepresentlines of depressions formed in the face of the sheet andarranged to cross each other-in this instance at right angles. Theseform by intersection elevations b b, which rise a little above thenormal level of the sheet, 0 as shown in the margin 0.

The compression of the sheet adds strength to it, and the displacementof material imparts elasticity to the elevations upon which the carpetrests-for example, when the fabric is used (No model.)

' as a lining. The lowersmooth face of the fah- 5 ric rests fiat uponthe floor.

Corrugated linings-that is to say, those in which an elevation on oneside registers or coincides with a depression on the other sideare soonflattened by pressure, as the eleva- 5o tions have no base to supportthem, and the elevation being compressed is not of course soft andelastic.

We are of course fully aware that linings composed of two sheets ofpaper with an interposed fibrous filling arranged in strips or bars havebeen proposed, and we make no claim to these. We are also aware that aperforated sheet of paper has been pasted to an unperforated sheet toform a cellular lining; but these are hard and stiff, and are liable tosplit in use and the dust to get between the sheets. Our fabric ishomogeneous and not composed of several elemental fabrics. Such liningsare comparatively expensive, and are not, we believe, so dnrable'asours.

Having thus described our invention, we claim- 1. As an improved articleof manufacture, a fabric made from'one sheet of felted material, havingdepressions formed by compression in one face only, and elevationsbetween said depressions, substantially as specified.

2. As an improved article of manufacture, a carpet-lining made from asingle sheet or thickness of felted material, and having depressions andelevations formed in and on one side only by means of compression,substantially as set forth.

In witness whereof we have hereunto signed our names in the presence oftwo subscribing witnesses.
